If menstrual cramps are so painful that you break out in a cold sweat, it is recommended to take hot ginger sugar water or brown sugar water orally, which can promote the discharge of menstrual blood and relieve the symptoms of menstrual cramps, or take oral painkillers, such as ibuprofen granules or codeine phosphate extended-release tablets to relieve menstrual cramps. If oral medication is not effective, you can inject morphine injection or atropine to relieve dysmenorrhea. Menstrual cramps that are so painful that you break out in a cold sweat are more likely to be pathological, such as the presence of adenomyosis, a condition in which the endometrium is ectopic to the myometrium, causing menstrual cramps that are very severe and unbearable. If there are fibroids, it may also cause dysmenorrhea. You need to go to the hospital for pelvic ultrasound and gynecological examination to help diagnose and give symptomatic treatment to relieve dysmenorrhea according to different causes.
